Using blue light technology to strengthen hygiene control and reduce manual disinfection needs in pharmaceutical production environments.
Phillips-Medisize, part of the global Molex group, provides design and manufacturing services for the pharmaceutical, diagnostics and medical technology sectors. The company tested Spectral Blue continuous disinfection technology at a production facility specializing in the manufacture of plastic components. The goal was to evaluate whether blue light could support cleaner conditions while reducing the need for daily manual disinfection.
After installing Spectral Blue devices and decreasing manual cleaning to once per week, surface microbe counts remained consistently low. The test demonstrated that blue light can effectively complement traditional cleaning methods and reduce labour-intensive disinfection routines without compromising cleanliness or safety.
Supporting safe and controlled manufacturing environments
Pharmaceutical and medical device manufacturing requires clean and stable environments to reduce the risk of contamination. Manual disinfection is essential, but high-frequency cleaning demands resources and increases operational workload.
The test at Phillips-Medisize sought to verify whether continuous blue light disinfection could:
- maintain low microbial levels
- reduce manual cleaning frequency
- improve consistency in hygiene control
- support high-quality production processes
The results indicated that Spectral Blue technology can function as a reliable supplementary method for maintaining surface hygiene in production spaces.
A simple and scalable system for daily hygiene control
The Spectral Blue units were installed above working areas where regular manual disinfection had previously been required. The system operates with visible blue light, making it suitable for continuous use in occupied areas without disrupting production.
Once the lights were installed, the facility reduced manual disinfection from daily rounds to once per week. Microbial monitoring showed that the hygiene level remained equally stable, confirming the system’s effectiveness even with significantly less manual intervention.
Improving operational efficiency and workplace safety
By lowering the need for frequent manual cleaning, the facility achieved measurable operational benefits:
- reduced labour and time spent on manual disinfection
- stable hygiene levels maintained throughout the week
- less disruption to production workflows
- improved safety and working comfort for personnel
For Phillips-Medisize, the test demonstrated the potential for integrating blue light disinfection into broader facility hygiene strategies, especially in environments where continuous surface cleanliness is required.
Long-term value for controlled environments
Spectral Blue technology offers a practical method for supporting contamination control between manual cleaning rounds. For facilities with demanding hygiene requirements, it can:
- improve stability in microbial levels
- reduce cleaning workload
- enhance environmental quality
- support compliance with internal hygiene protocols
The test at Phillips-Medisize showed that advanced light-based disinfection can strengthen overall cleanliness without increasing maintenance demands.
